Benefits of technology

The present invention aims to solve the problems of previous configurations where the motor sticks out and interferes with other structures. The invention provides a reducer that compactly forms the layout configuration of an apparatus and prevents interference between the motor and other structures. Additionally, the invention allows for easy adjustment of the rotational force generated by the motor and transferred to the pinion shaft through adjustment of the number of teeth in the step gear, fixed ring gear, or movable ring gear.

Problems solved by technology

Thus, when the components are equipped in a vehicle, the motor inevitably protrudes to interfere with other structures, which is disadvantageous in terms of the layout.

Abstract

Disclosed are a reducer and an electric power steering apparatus having the same. According to the present invention, an input shaft, a driving shaft, and a pinion shaft are coaxially arranged. Thus, a conventional configuration, in which a motor inevitably protrudes, can be improved to prevent the motor from interfering with the other structures. Therefore, a layout configuration in an apparatus can be compactly formed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2013-0040763, filed on Apr. 15, 2013, which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a reducer and an electric power steering apparatus having the same, and more particularly to a reducer which improves a conventional configuration, in which a motor inevitably protrudes since a motor shaft, an input shaft, a driving shaft, a pinion shaft, etc. are coaxially arranged, to be capable of preventing the motor from interfering with other structures such that a layout configuration in an apparatus can be compactly formed, and an electric power steering apparatus having the reducer.[0004]2. Description of the Prior Art[0005]FIG. 1 is a view illustrating a configuration of a conventional electric powe...
